My, invention.- relates to telescopic umbrellas comprising telescopic stick-shaped partsand-teles seopic head bar members.

Object of the present. invention is to. provide a telescopicumbrella the main struts of which are supported by auxiliary struts,- thus forming an umbrella-frame capable of being shortened and. having the advantage of simple structure and reliable operation. The topgpart or crown ofthe umbrella is onlyconnect-ed to upper telescopic head bar members, and lowertelescopic head bar members are only supported by a single main strut each extending to a main sliding sock et,- theauxiliary strut of:isaid main strut leading to an upper fast stick part.

A further object of the invention-is toprovide a collapsible umbrella wherein. coactingstick sections and coacting. rib members? are adapted tube-simultaneously telescoped- A-still further object of the invention"is?to pro::- vide a collapsible umbrella comprising telescopmg. stick sections.andtelescoping rib members with bracestruts, and wherein the rib-members are centrally connected to a crownintspacedirelaticnztothe stick sections.

Another. object of the invention: is to; secure the telescopic. head barl members in their pulled-- out position one against each other by means- 0f a projection or bulge upon a hollow rail of the upper head bar member so that the top part or crown and,-thus, the: upper head barmembers are clamped one against'each other: I

For opening the umbrella it is first necessary topull outthe head bar members only. in.conti'ary'to priorart umbrellas ofthis type. which require'a telescoping of "both the stick parts and thelheadbar members at thesame time. Asia result'iofthis structural'featureit is obtained i a light running telescoping operation. Moreover the .umbrella aecordingto. this-invention-has :the further advantage that it'canbe openedin any position, i. e. even if directed upwards. The smallest displacing movement of the main sliding socket effects a radial outward movement of the head bars, as the auxiliary struts are supported by the top of the stick. A preliminary shaking of the umbrella for the purpose of straddling the head bar members is avoided by this structure. The umbrella-frame comprises a few parts only so that the structure is simple and the operation positive. Any auxiliary devices for opening or closing the umbrella are not necessary.

By way of example, the structural features of the telescopic umbrella redesigned according to this invention are set forth in the following specificationand will .be-better understood bygpractls tioners from the accompanying. drawings in which;

The telescopic-umbrella according to. this im vention shown .by way :of example in Figures-1 to 6; comprises:

An upper stick part I is adapted to be---telescoped into aslower stick-part Z-aswell as-lower head bar members- 4 into upper head bar--.mem+ hers}; The. upper head bar members mhave the. shapeofhollow rails enabling the lower head barmembers Lhavingtheshape of :solid IQiISztQ slidetherein. Main struts 5! connect a runner or socket {with the top ,of the upper--or-outer head bar members 4 by meansof so-calledshinge members9. Auxiliary struts I are hinged to the main-struts 5,.their free ends being. fastenedeto the upper stick part' I. Thetelescopic upper-head b'a'rmembers 3 are heldtogether by a top part-or crown 8" being" nowhere else connectedsto.- any other part of the umbrella-frame. Intheupper positionv the runner or socket-6 supportedby,

aspring ID in known manner.. Atset spring. H mounted in the upper stick p-art-lsecuresthe lower position of the runner or socket 6. Theset spring A I l is rounded at its twov edgesand: provided withanotch l2'in its middle partadapted to engage the runner or socket 6. The rounded parts of the set spring H are formed with sharp, straight-lined shoulders I3a, [3b at both sides, thus making possible to secure the stick parts I, 2 either in pulled-out position shown in Fig. 4 or in telescoped position shown in Fig. 2. As shown in Fig. 2 the lower end of the stick part 2 is provided with a slot enabling the set spring II to project through the stick part 2 when the stick parts are telescoped one into another. As usual the lower part of the stick part 2 is equipped with a handle [4.

The upper head bar members 3 are provided with a projection or bulge 15 so as to secure the telescopic head bar members 3, 4 in pulled-out position. Said projection or bulge [5 effects a clamping action when the hinge member 9 connected to the lower head bar members 4 slides over the projection or bulge t5, thus preventing both an undesirable moving of the upper head bar members 3 along the lower head bar members 4 as well as a rigid condition of theumbrella during the position shown in Fig. 2. l

The operation of the telescopic umbrella according to the invention described with reference to Figures 1 to 6, is as follows:

By pulling out the top part or crown 8 the head bar members are pulled out so that the umbrella is brought from the telescoped position shown in Fig. 1 to the position according to Fig. 2. Then the runner or socket 6 is pressed upwards so that it attains its upper working position. As a result of this, the stick parts are pulled out at the same time until the umbrella is entirely opened occupying the position shown in Fig. 4. In that opened position the self-centering top part or crown 8 lies against the upper stick part I. During the closing movement the runner or socket 6 is moved downwards at the same time pressing the set spring II with its rounded portions I3a, I 317 into the upper stick part i. As a result of this, the stopping of the stick parts at the lower edge 13b is released at the same time. A further displacing of the runner or socket S then efiects the telescoping of the upper stick part I into the lower stick part 2 until both stick parts have attained the position shown in Fig. 2: In this manner described the umbrella according to the invention is opened or closed as an umbrella of usual type. The stick parts are shifted during the closing respectively the opening operation. For shortening the umbrella merely the head bar members are telescoped by a light blow after overcoming the clamping action of the projection or bulge I5.

The manner of using and applying 'the illustrative embodiment of my invention set forth above will be clear from the foregoing description. It is, of course, to' be understood that my invention is not limited to the specific embodiment thereof here shown and described for purposes of illustration only.
